I see.

No, I think it was just implemented that way because it was simple.  As
somebody said in this thread, those functions should be rewritten
"inside out" -- i.e., separate out the stuff inside those commands that
actually generate the text to that they can be reused.  I'll have a go
at doing that...

No, it's written in that hand-wavey way because the %s there may be a
getter function -- it might not be a variable.  It could be rewritten to
use totally different sentences in the variable vs. getter cases,
though.
